[#58]

Add full CRUD operations for dashboards and synthetics.

New Commands

Dashboards

# Create a dashboard from JSON file
newrelic-cli dashboards create --from-file dashboard.json

# Update an existing dashboard
newrelic-cli dashboards update <guid> --from-file dashboard.json

# Delete a dashboard (with confirmation prompt)
newrelic-cli dashboards delete <guid>
newrelic-cli dashboards delete <guid> --force  # skip confirmation

Synthetics

# Create a synthetic monitor from JSON file
newrelic-cli synthetics create --from-file monitor.json

# Update an existing monitor
newrelic-cli synthetics update <monitor-id> --from-file monitor.json

# Delete a monitor (with confirmation prompt)
newrelic-cli synthetics delete <monitor-id>
newrelic-cli synthetics delete <monitor-id> --force  # skip confirmation

JSON File Examples

Dashboard JSON

{
  "name": "My Dashboard",
  "description": "Optional description",
  "permissions": "PUBLIC_READ_WRITE",
  "pages": [
    {
      "name": "Page 1",
      "widgets": [
        {
          "title": "Transaction Count",
          "visualization": {"id": "viz.line"},
          "layout": {"column": 1, "row": 1, "width": 4, "height": 3},
          "rawConfiguration": {
            "nrqlQueries": [{"accountId": 123, "query": "SELECT count(*) FROM Transaction"}]
          }
        }
      ]
    }
  ]
}

Synthetic Monitor JSON

{
  "name": "Homepage Check",
  "type": "SIMPLE",
  "frequency": 10,
  "status": "ENABLED",
  "uri": "https://example.com",
  "locations": ["AWS_US_EAST_1", "AWS_US_WEST_1"]
}

Safety Features (Delete Commands)

Both delete commands include:

1. Confirmation prompt by default - Shows resource name before deletion
2. --force flag - Skip confirmation for automation
3. Resource lookup first - Fetches the resource to display its name

Test Plan

• Build passes: make build
• Tests pass: make test
• dashboards create --help shows JSON structure and examples
• dashboards update --help shows usage
• dashboards delete --help shows usage
• synthetics create --help shows JSON structure, monitor types, and locations
• synthetics update --help shows usage
• synthetics delete --help shows usage
